Ten ports can support 10-GbE or 1-GbE. The other eight ports can flexibly support HiGig2/HiGig+/ HiGig/10-GbE/1-GbE. Additionally, the BCM56801 integrates all the SerDes required to interface to applicable copper and fiber physical interfaces. The integrated SerDes functionality includes 10-Gbps XAUI and 1-Gbps SGMII PHY interfaces. The integrated SerDes complies with the CX-4 standard and PICMG3.1 standard, which ensures interoperability with Ethernet line cards in an Advanced TCA chassis. With 196 Gbps of aggregate switching bandwidth, the BCM56801 represents the highest level of Ethernet switching integration in the industry. This integration allows embedded switching vendors to provide next-generation products at 10-GbE speeds, as well as an ideal fit into current design form factors. This capability has many benefits, including reducing vendor development cost and creating additional value in current generation systems through upgradability. The BCM56801's low power dissipation simplifies board design and optimizes vendor board space. The advanced ContentAware engine supports ToS/DiffServ, policybased routing, priority tagging, and remapping. The advanced packet filtering and classification functions of the BCM56801 make it a seamless fit utility for computing applications where user segregation and network security is critical. In addition, the BCM56801 provides advanced security features that improve network resiliency and reliability. Moreover, the BCM56801 features advanced load balancing functionality that uses flow information to provide high-percentage link utilization. The BCM56801 supports L2 switching with 4K VLANs, IPv4, and IPv6 full routing functionality, enabling it to become a direct extension of the enterprise network. This provides additional customer value by eliminating the hardware and management costs of maintaining intermediate routers. As the latest member of the StrataXGS switch family, the BCM56801 Software Development kit preserves software continuity with Gigabit Ethernet switches, reducing development cost and shortening the product time-to-market. The BCM56801 implements congestion handling features such as HeadOf-Line blocking prevention and IEEE 802.3x flow control. In addition to a 32-bit PCI interface used to communicate with a local CPU, the BCM56801 supports an I2C controller for communicating with external devices such as serial EEPROM, flash memories, and parallel port devices. The BCM56801 relies on Broadcom's modular switching architecture to provide intelligent packet processing, network security and enhanced manageability at a low cost. The BCM56801 is an ideal solution for nextgeneration, high-speed embedded switching applications, such as Blade Servers and Advanced TCA computer platforms. Together with the BCM56700 as a centralized fabric, the BCM56801 can also be used to build cost-effective high-density 10-GbE switches.
